Connecticut CDL basics
- A Connecticut commercial learner permit is valid for one year. If you do not get a CDL in that time, you pass all the required tests again for a new permit.
- The minimum age is 18 for driving inside Connecticut and 21 for driving between states or hauling hazardous materials.
- You bring a valid Connecticut driver's license, REAL ID documents, your Social Security number and your printed self-certification confirmation to the knowledge test.
- The general knowledge test has 50 questions and you need 40 correct to pass.
- Knowledge tests are taken at DMV offices by appointment only.
Connecticut can add its own rules on top of the federal manual. Check the official site for Connecticut DMV before your test. DMVZone is not affiliated with any state agency.
